👉 Semihardy is a term used in mathematics to describe a group of objects that are both "semi-homogeneous" and "semi-hereditary." It is often used in the context of algebraic structures, particularly in the study of Lie algebras. A semi-homogeneous group is one where every element has an inverse, and a semi-hereditary group is one where all subgroups are normal. Semihardy groups have been studied extensively due to their connections with Lie theory
